I've recently installed PP3 on my comptuter - I already had PP2 with AspectHd v5.0 in my computer - when I load a CINEFORM project file, the CINEFORM windows shows that I'm using AsepctHD v4.3, which isn't even on my computer...!?!

Now I have desinstalled PP2 and AspectHd v5.0 and reinstalled AspectHD v5.0, but PP3 still shows v4.3...

Any thoughts on that or person experiencing the same problem ?

This issue is currently in open open ticket with CINEFORM and I'll post it on CINEFORM's forum too.

I suggest removing all references to Cineform from your system and trying to install it again.

What is the name of the file you are using to install it? Are you 100% sure you are installing v5? I hate to even mention it but I have had no problems installing v5 and the newest version installs on to ever version of Premiere Pro you have on your PC according to the release notes for the latest builds.
